Before he was found dead at a lodge in Texas on February 13, he took a hunting trip with members of a secret society known as "The International Order of St. Hubertus," according to the Washington Post.

The men-only hunting club, which dates back to the 1600s, has the motto: "Honoring God by honoring His creatures." Members wear plush dark green velvet robes with cherry lining and some hold titles like "knight" and "grandmaster."

The Cibolo Creek Ranch, where Scalia was found dead, is owned by millionaire John Poindexter, a leader in the International Order of St. Hubertus, according to the Washington Post. It is not clear if Scalia was affiliated with the group.

It has also emerged that a breathing machine used to treat sleep apnea was found on Scalia's bedside table.

According to the police report: "The hose for the machine was resting on the edge of the bed. The breathing machine was switched off and the hose was not connected to Scalia."

The 79-year-old, who was remembered at a funeral last weekend, suffered from heart disease, obesity and diabetes, a Supreme Court doctor has said. Authorities say nothing was suspicious about his death.
